Dry Eye Syndrome (Keratoconjunctivitis Sicca): Surgical Therapy

If tear substitute therapy is not sufficient, sclerotherapy of the lacrimal puncta may be helpful. The lacrimal puncta direct tear fluid to the draining tear ducts. If they are sclerosed, the tear fluid flows more slowly, which leads to relief of the symptoms. A temporary closure of the lacrimal puncta with small collagen or silicone plugs (punctun plugs) can also help. This is effective in severe hypovolemic dry eye.
